As for Deadmau5, the 31-year-old Canadian electro-house music master said he needed time to think.

"Going to spend a little while screwing my head back on. I guess I'm not cut out for relationships right now," he Tweeted Saturday. "I'll figure it out. No hard feelings."

The couple, dubbed "Kat and Mau5" (mouse), were first spotted together in September, and the pair fell hard and fast (the deejay called Kat "The love of my life" just one month later) - a contributing factor in their breakup, according to Deadmau5.
